68 1/2 Super Stockers rear rim size .....
« on: September 25, 2018, 05:16:57 pm »
I know this is a long shot but I been plugging away at cloning one of the 68 Winternationals cars, found most of the hard/impossible parts but I'm trying to figure out what size rear rims the cars with the plain chrome rear rims (with the Cragar center caps ) used. I plan on trimming the quarters and shortening the rocker moulding but I have no idea what size rim they used. I found several sets of NOS "Chrome Reverse" wheels from back in the day, but don't want to pull the trigger on anything till I know what size rims I need.

Any Ideas ??

Thank's in advance , John

You might want to PM 161854.  If anyone would remember it would probably be him.

Thanks Rusty, just the info that I needed, it looks from your Pic that it's a 14" rim, That's the ex Hubert Platt car, correct ? The HM cool can I  have reportedly came from one of Hubert's cars......

You don't by chance remember what size tire you ran back then ?

Awesome , Thanks.   I'm running Cragar SS's on the front, just picked up a set of 15x4 wheels (1970 dated)      I've been collecting this stuff forever and I've never seen a set of skinny Keystone Classics in real life like your running in that pic. They gotta be scarce as hell....

Thank's again, John

     The tire sizes for the S/S cars was 8.90x15 and were Goodyears. They were on 6" wide chrome wheels also made by Cragar. The 8.90x15 tire still had fairly stiff sidewalls and the thought "then" was to run them on narrow rims and lower pressure ( 10-12 psi) to increase the "footprint". Firestone had yet ( as of '68) to introduce their 2ply "Drag 500" tire that REALLY made a difference in traction. Firestone was a FAR superior tire to the Goodyear until about 70-71 when they figured out the 2 ply side wall deal. "Stock" eliminator was limited to a 7.50 "dual groove" slick in either 14 or 15". All of the factory cars were competing is Super Stock and had the 8.90x15s.
    8.90 Goodyears are VERY hard to find these days.

Hi Randy, These look like the closest new tires I can find.....

https://www.cokertire.com/tires/styles/drag-tires/vintage-drag-slick-900-15.html

I'm hoping to find the right rim (width and offset) that will look correct and not require major wheelhouse mods. I've went to a lot of effort to get things right but realize I've got to make some concessions cause I plan on racing the car. most of the concessions so far are not visible (big crank, cam, clutch, axles) . Only part I will probably have an issue with is the roll bar (an NOS vintage Lakewood 3 point bar) as NHRA won't recognize 3 point bars ……..

     The tire depends on which class you are going to build for , same as the rollbar. The tire pictured is a "stock" class tire with 7" "tread" width. Stock classes did NOT have to run with a roll bar.  For Super Stock a roll bar WAS mandatory and the wider tire was legal along with the non grooved wider "tread" width slicks. The wheel offset was "zero" to allow the tire to fit in the stock wheel opening. The 10.50 Goodyear tire was not run on any '68 Winternationals entry. The tire used was the 8.90x15. The 10.50 tire required "bumping" the front portion of the wheel opening which NHRA wouldn't allow until later . The two ply Firestone on Rusty's car in the above picture came out in '70 (IIRC) and by that time the tire rules had relaxed to where a 12" "tread" was the maximum allowable width. Stock still had to run a "two groove" 7" tire until '75 when the current 9" maximum was allowed.  Super Stock is now open on Maximum tire size.

So the modified quarters came later ?   All the cars I've seen have the quarters "bumped" and the rocker moulding shortened, even the restored Rice and Holman car.

(This would be great news as I really don't want to cut NOS rocker mouldings)

I assume you are cloning the SS cars.  I noted on the starting line at the reunion that on most 68's the rear suspension was so high that even on a hard start the tire did not move up into the wheel well very much. I examined the wheel lip on the SS cars and it was obvious it was rounded (rolled) a lot.
I like large rear tires but like lower ride heights so will have to use moderation on tire/wheel size on my 68.

A roll bar was not needed in Super Stock when I raced my 1969 Mustang in the 70's. When I decided to race it in the 90's in Stock I had to add a roll bar.

From looking at all the Pic's I could find that were taken at the Winternationals (or soon after) , It appears that all the cars with the exception of Hubert Platts C/SA stocker ( #984) had a 3 point bar installed. It appears that it was a standard Lakewood 3 point bolt in bar. Vinnie Lyons 135 car (The Rye Ford car)  also had/has a Lakewood bar installed from day one.

You should try and find a vintage Lakewood 3 point bar for a Mustang today .....  ( Camaro and Nova bars turn up occasionally but one for a mustang is Tough)
